topic.<BR>Some years ago I attended an advanced Access three day course to get
my<BR>head around this database program.<BR>We were told in no uncertain way,
that one should NOT use number as a<BR>data type for phone numbers or
postcodes etc. In fact it should only be<BR>used when you intend doing
mathematical calculations with it's contained<BR>data further down the
track.<BR>Therefore, I choose A for Qu 15 (Part A), but in doing so remember
one<BR>or more of the VITTA practice ITA exams that indicated it should
be<BR>number.<BR>What do others think?<BR>Keith<BR>Keith Richardson<BR>ITA
